' CONCRETE FORM BRACKET Filed May 17, v1943 ATTDRNEYE Patented June 18,1946 UNITED STATES PATENT OFFICE 2 Claims.

My invention relates to concrete forms, and has among its objects andadvantages the provision of an improved bracket particularly well suitedfor supporting the usual horizontal studding member on the verticalstudding. At the present time, it is a common practice to cut woodenblocks and nail them to the vertical studding. This entails considerablework and is expensive. Nails frequently split the short blocks, andrender the same unsuitable. In addition, such splitting of the woodrenders the beams unsafe as a walk for the workmen. Accordingly, anobject of my invention is to provide a bracket which is easily attachedto the usual vertical studding for supporting the horizontal studdingmember, the latter being known in the trade as a waler, purlin, orstifener, wherein the bracket embodies novel means to facilitatepositioning of the bracket in a correct horizontal position, and inwhich the bracket may be reused from time to time. The term "studding inthe instant case is employed in lieu of the foregoing trade terms.

In the accompanying drawing:

Figure 1 is a cross sectional view of a conventional concrete formillustrating my invention applied thereto.

Figure Z is a face view of the bracket.

Figure 3 is an edge view, and

Figure 4 is a View of an opposite edge.

In the embodiment of the invention selected for illustration, Figure 1illustrates a concrete form I such as is employed in the construction ofa concrete wall or foundation I2. This form includes the usual sheathingor boards I4 between which the wet concrete is poured. These walls aresupported by vertical studding I6 and the horizontal studding I8, thelatter lying edgewise against the studding I6. This structure is old andwell known in the art. My invention relates to the bracket 2l! forsupporting the studding I8 with respect to its vertical position on thevertical studding.

In Figure 2, the bracket 20 is cut from sheet metal and has the contourof a right triangle. The edges 22, 24, and 26 are respectively providedWith notches 28. The notches 28 in the edge 22 are horizontally alignedwith the notches 28 in the edge 26. The edge 24 is arranged at rightangles to the edge 22, and the notches 28 in the edge 24 alignvertically with notches 30 in the edge 26. 1

Two nail receiving openings 32 are provided in the bracket 20 adjacenteach of the edges 22 and 24. N ear the corner dened by the intersectionof the edges 22 and 24 is. located a large opening 34 of such size as tofreely receive the head of nails such as may be used on the job. Thisopening communicates with a slot 36 of nail receiving proportions butsufficiently narrow to prevent the nail heads from slipping through.

.In operation, the nails 38 are driven into the vertical studding I6.The brackets 20 are then hung on the nails. Additional nails 40 aredriven through at least two of the openings 32, but after the bracketshave been aligned to position their upper edges horizontally. `Suchalignment of the bracket is easily attained by bringing one notch 28 inthe edge 24 vertically of the corresponding notch 30 in the edge 26,which may be determined by bringing the two coacting notches intoregistration with an edge of the vertical studding I6. The notches 28and 30 in the edge 26 respectively cooperate with the notches 28 in theedges 22 and 24 in such manner that either edge 22 or 24 may bepositioned horizontally for supporting the studding or beams I 8.

The nails 40 in most cases will extend through the studding I6. Thusthese nails may be easily driven back some distance to facilitate theirremoval.

Without further elaboration, the foregoing will so fully explain myinvention, that others may, by applying current knowledge, readily adaptthe same for use under various conditions of service.

I claim: A Y

1. A bracket for supporting horizontal studding on vertical studding,comprising a flat body at least one corner of which is a right angle,the body having relatively spaced openings therein for attaching saidbody to the vertical studding at two or more spaced points near thevertically disposed edge leading from said corner, the other edge of thebody leading from said corner supporting the horizontal studding, andall of the respective edges of said body being notched at points whichwould mark the termination of groups of spaced parallel lines if drawnwith the lines in one group paralleling one edge leading from saidcorner, and the other group paralleling the other edge drawn from saidcorner, said notches functioning to accurately and quickly position thebracket.

2. A triangular bracket for supporting horizontal studding on verticalstudding, the body of which is at, and designed to be arranged with thetwo edges representing the sidest of the triangle on the verticalstudding, and beneath and supporting the horizontal studding, with theedge representing the hypotenuse of the triangle leading from the baseof the bracket to the joint adjacent the center face of the horizontalstudding, and guide marks on all of the edges of the bracket positionedat the termination of spaced parallel imaginary lines drawn inassociated groups each parallel with an edge of the bracket representinga side of the triangle.
